Pharmacologic Properties:
Epinephrine is a sympathomimetic which stimulates both alpha and beta adrenergic receptors. Its effects are to increase systemic vascular resistance, arterial blood pressure, coronary and cerebral blood flow, heart rate and contractility. The alpha-adrenergic effect increases vascular resistance and coronary blood flow, which may make the fibrillating myocardium more susceptible to counter-shock. The beta adrenergic effect increases heart rate and cardiac output, and induces bronchodilation.

- Severe bronchospasm (wheezing) associated with Asthma or COPD exacerbation
